hello everyone and a Happy New Year. I wanted to have some information about the assembly of an oil vapor filter, it is not difficult but I did not understand if I should remove the non-return valve fig.7? i will put a cap in the intake manifold this is okey but on the side of the vapor tank, do i have to leave it open anyway? one last thing, what diameter is the pipe where to insert the filter? thanks.
You should leave the connection between intake manifold and the tank as the vacuum helps draw out the oil from the breather outlet on the cam cover (No.2). I have tried set ups involving the disconnection to the No.3 pipe before...and can't say that there is any improvements to performance. If you are getting excessive oil in your intake, I would check the valve (No.7) first. If you can blow through it, the valve needs replacing....and also check the health of the engine or the viscosity of oil you are using.
i am trying to build my own custom SIP. i try to eliminate some input if possible, like for example the tube in question by adding a filter. I only have the EBV pipe and the petrol vapor pipe left. I think I can cancel the EVB pipe, because I have a manual boost controller, I don't know if the injector light could appear, as far as the petrol vapor pipe is concerned, you can perhaps also put them 1 filter?
You can put a filter...I've done that before in the past. But I get a feeling that its more difficult for the engine to get rid of its oil vapors that way. I believe that when the turbo spools, it helps pull the vapors from the catch tank. I would keep set ups as close as possible to stock...but of course that is entirely up to you.
